My Xavier's fan does not work

As title , my Xavier work, but its fan does not work, so Xavier is very hot.
How about your Xavier?

Hi, did you check the voltage input to fan connector? You can download the SCH/PCB file from DLC to locate the fan connector and check.

What happens when you run the jetson_clocks.sh script in the default home directory? One of the things that script does is activate the cooling fans.

I will try it, thank you
